BACKGROUND

The present disclosure relates generally to crystalline solid forms of the antiviral compound 4-amino-2-butoxy-8-(3-(pyrrolidin-1-ylmethyl)benzyl)-7,8-dihydropteridin-6(5H)-one, processes for making the forms, and their therapeutic methods of use.

The innate immune system provides the body with a first line defense against invading pathogens. In an innate immune response, an invading pathogen is recognized by a germline-encoded receptor, the activation of which initiates a signaling cascade that leads to the induction of cytokine expression. Innate immune system receptors have broad specificity, recognizing molecular structures that are highly conserved among different pathogens. One family of these receptors is known as Toll-like receptors (TLRs), due to their homology with receptors that were first identified and named in Drosophila, and are present in cells such as macrophages, dendritic cells, and epithelial cells.

There are at least ten different TLRs in mammals. Ligands and corresponding signaling cascades have been identified for some of these receptors. For example, TLR2 is activated by the lipoprotein of bacteria (e.g., E. coli.), TLR3 is activated by double-stranded RNA, TLR4 is activated by lipopolysaccharide (i.e., LPS or endotoxin) of Gram-negative bacteria (e.g., Salmonella and E. coli O157:H7), TLR5 is activated by flagellin of motile bacteria (e.g., Listeria), TLR7 recognizes and responds to imiquimod and TLR9 is activated by unmethylated CpG sequences of pathogen DNA. The stimulation of each of these receptors leads to activation of the transcription factor NF-κB, and other signaling molecules that are involved in regulating the expression of cytokine genes, including those encoding tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), and certain chemokines. Agonists of TLR-7 are immunostimulants and induce the production of endogenous interferon-α in vivo.

There are a number of diseases, disorders, and conditions linked to TLRs such that therapies using a TLR agonist are believed promising, including but not limited to melanoma, non-small cell lung carcinoma, hepatocellular carcinoma, basal cell carcinoma, renal cell carcinoma, myeloma, allergic rhinitis, asthma, COPD, ulcerative colitis, hepatic fibrosis, and viral infections such as HBV, Flaviviridae viruses, HCV, HPV, RSV, SARS, HIV, or influenza.

The treatment of Flaviviridae virus infections with TLR agonists is particularly promising. Viruses of the Flaviviridae family comprise at least three distinguishable genera including pestiviruses, flaviviruses, and hepaciviruses (Calisher, et al., J. Gen. Virol., 1993, 70, 37-43). While pestiviruses cause many economically important animal diseases such as bovine viral diarrhea virus (BVDV), classical swine fever virus (CSFV, hog cholera) and border disease of sheep (BDV), their importance in human disease is less well characterized (Moennig, V., et al., Adv. Vir. Res. 1992, 48, 53-98). Flaviviruses are responsible for important human diseases such as dengue fever and yellow fever while hepaciviruses cause hepatitis C virus infections in humans. Other important viral infections caused by the Flaviviridae family include West Nile virus (WNV) Japanese encephalitis virus (JEV), tick-borne encephalitis virus, Junjin virus, Murray Valley encephalitis, St Louis encephalitis, Omsk hemorrhagic fever virus and Zika virus. Combined, infections from the Flaviviridae virus family cause significant mortality, morbidity and economic losses throughout the world. Therefore, there is a need to develop effective treatments for Flaviviridae virus infections.

The hepatitis C virus (HCV) is the leading cause of chronic liver disease worldwide (Boyer, N. et al. J Hepatol. 32:98-112, 2000) so a significant focus of current antiviral research is directed toward the development of improved methods of treatment of chronic HCV infections in humans (Di Besceglie, A. M. and Bacon, B. R., Scientific American, October: 80-85, (1999); Gordon, C. P., et al., J. Med. Chem. 2005, 48, 1-20; Maradpour, D.; et al., Nat. Rev. Micro. 2007, 5(6), 453-463). A number of HCV treatments are reviewed by Bymock et al. in Antiviral Chemistry & Chemotherapy, 11:2; 79-95 (2000). Currently, there are several antiviral compounds, ribavirin, a nucleoside analog, interferon-alpha (α) (IFN), and sofosbuvir, another nucleoside analog, that are used for the treatment of chronic HCV infections in humans. Ribavirin alone is not effective in reducing viral RNA levels, has significant toxicity, and is known to induce anemia. The combination of IFN and ribavirin has been reported to be effective in the management of chronic hepatitis C (Scott, L. J., et al. Drugs 2002, 62, 507-556) but less than half the patients given this treatment show a persistent benefit.

HCV is recognized by innate virus-sensing mechanisms that induce a rapid IFN response (Dustin, et al., Annu. Rev. Immunol. 2007, 25, 71-99). It is likely that the sources of the IFN are, at least, the infected hepatocytes and particularly the plasmacytoid dendritic cells (pDC) that highly express TLR 7 receptors and secrete high amounts of IFN. Horsmans, et al. (Hepatology, 2005, 42, 724-731), demonstrated that a once daily 7-day treatment with the TLR 7 agonist isatoribine reduces plasma virus concentrations in HCV infected patients. Lee, et al. (Proc. Natl. Acad. Sci. USA, 2006, 103, 1828-1833), demonstrated that TLR 7 stimulation can induce HCV immunity by both an IFN and IFN-independent mechanisms. These workers also revealed that TLR 7 is expressed in normal as well as HCV infected hepatocytes. These combined results support the conclusion that stimulation of TLR 7 receptors, such as through the administration of a TLR 7 agonist, is a viable mechanism for effectively treating natural HCV infections. Given the need for more effective treatments for HCV infections, there is a need to develop safe and therapeutically effective TLR 7 agonists.

Similarly, despite the existence of efficient vaccines, hepatitis B virus (HBV) infection remains a major public health problem worldwide with 400 million chronic carriers. These infected patients are exposed to a risk of developing liver cirrhosis and hepatocellular carcinoma (Lee, W. M. 1997, N. Eng. J. Med., 337, 1733-1745). Currently, there are believed to be approximately 1.25 million chronic hepatitis B carriers just in the United States, with 200,000 people newly infected each year by contact with blood or body fluids.

Hepatitis B virus is second to tobacco as a cause of human cancer. The mechanism by which HBV induces cancer is unknown, although it is postulated that may directly trigger tumor development, or indirectly trigger tumor development through chronic inflammation, cirrhosis, and cell regeneration associated with the infection.

Hepatitis B virus has reached epidemic levels worldwide. After a two to six month incubation period in which the host is unaware of the infection, HBV infection can lead to acute hepatitis and liver damage, that causes abdominal pain, jaundice, and elevated blood levels of certain enzymes. HBV can cause fulminant hepatitis, a rapidly progressive, often fatal form of the disease in which massive sections of the liver are destroyed. Patients typically recover from acute viral hepatitis. In some patients, however, high levels of viral antigen persist in the blood for an extended, or indefinite, period, causing a chronic infection. Chronic infections can lead to chronic persistent hepatitis. Patients infected with chronic persistent HBV are most common in developing countries. By mid-1991, there were approximately 225 million chronic carriers of HBV in Asia alone, and worldwide, almost 300 million carriers. Chronic persistent hepatitis can cause fatigue, cirrhosis of the liver, and hepatocellular carcinoma, a primary liver cancer.

In western industrialized countries, high risk groups for HBV infection include those in contact with HBV carriers or their blood samples. The epidemiology of HBV is in fact very similar to that of HIV, which accounts for why HBV infection is common among patients with AIDS or HIV-associated infections. However, HBV is more contagious than HIV. To ameliorate suffering and to prolong the lives of infected hosts new compounds and methods of treating AIDS and attacking the HIV virus continue to be sought.

The compound 4-amino-2-butoxy-8-(3-(pyrrolidin-1-ylmethyl)benzyl)-7,8-dihydropteridin-6(5H)-one, designated herein as Compound I, as described for example in WO 2010/077613 and U.S. Pat. No. 8,367,670, has been reported to be an inhibitor of toll-like receptor 7. Moreover, Compound I is being investigated for use in treating HBV and HIV. However, Compound I was not previously known in any crystalline form.

Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to ²H (deuterium, D), ³H (tritium), ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸F, ³¹P, ³²P, ³⁵S, ³⁶Cl and ¹²⁵I. Various isotopically labeled compounds of the present disclosure, for example those into which radioactive isotopes such as ³H, ¹³C and ¹⁴C are incorporated. Such isotopically labeled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of patients.

The disclosure also includes Compound I in which from 1 to “n” hydrogens attached to a carbon atom is/are replaced by deuterium, in which n is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism and are thus useful for increasing the half-life of any Compound I when administered to a mammal. See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism”, Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogen atoms have been replaced by deuterium.

Deuterium labeled or substituted therapeutic compounds of the disclosure may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. An ¹⁸F labeled compound may be useful for PET or SPECT studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. Further, substitution with heavier isotopes, particularly deuterium (i.e., ²H or D) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements or an improvement in therapeutic index. It is understood that deuterium in this context is regarded as a substituent in Compound I.

The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen”, the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.

When Form XII is dried in a reduced atmosphere environment, the reduced atmosphere can have any suitable pressure less than 1 atmosphere, such as 0.9 atm, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1, 0.05, 0.01, 0.005, 0.001 atm, or less. In some embodiments, preparing Form XIV includes drying Form XII at a pressure less than 1 atmosphere. In some embodiments, preparing Form XIV includes heating Form XII. In some embodiments, preparing Form XIV including drying Form XII at a pressure less than 1 atmosphere, and heating Form XII at a temperature of about 40° C.

The method of preparing crystalline Compound I can be carried out at temperatures generally from about 0° C. to the reflux temperature of the solvent. In some embodiments, the temperature can be room temperature. Alternatively, Compound I, or one of the crystalline forms of Compound I, can be heated in solid state form. For example, Compound I Form I can be heated to a temperature of from about 130° C. to about 200° C., or from about 130° C. to about 150° C. Compound I Form II can be heated to a temperature of from about 90° C. to about 200° C.

When multiple solvents are used in the methods of the present invention, the ratio of solvents in the above methods can be any suitable ratio from about 1:1 to about 1:9, including about 1:2, 1:3, 1:4, 1:5, 1:6, 1:7 and about 1:8 by volume. The range of solvent ratios is preferably from about 1:1 to about 1:9, more preferably from about 1:2 to about 1:7, even more preferably from about 1:2 to about 1:5 by volume.

The ratio of Compound I to solvent, can be any suitable ratio to promote crystallization. For example, the Compound I to solvent ratio can be from about 1:5 (weight/volume, or w/v) to about 1:50 (w/v), including about 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:20, 1:25, 1:30, 1:35, 1:40 and about 1:45 (w/v). The Compound I to solvent ratio is preferably from about 1:10 to about 1:25 (w/v), more preferably from about 1:10 to about 1:15 (w/v).

Crystallization can be induced by methods known in the art, for example by mechanical means such as scratching or rubbing the contact surface of the reaction vessel with e.g. a glass rod. Optionally the saturated or supersaturated solution may be inoculated with seed crystals. The mixture for crystallizing Compound I can also contain a seed crystal of crystalline Compound I.

Isolation of the desired crystalline form can be accomplished by removing the solvent and precipitating solvent from the crystals. Generally this is carried out by known methods, such as, filtration, suction filtration, decantation or centrifugation. Further isolation can be achieved by removing any excess of the solvent(s) from the crystalline form by methods known to the one skilled in the art as for example application of a vacuum, and/or by heating.

V. PHARMACEUTICAL COMPOSITIONS

The solid forms of Compound I provided herein can be administered in the form of pharmaceutical compositions. This disclosure provides pharmaceutical compositions that contain, as the active ingredient, one or more of the solid forms of Compound I described or a pharmaceutically acceptable salt or ester thereof and one or more pharmaceutically acceptable excipients, carriers, including inert solid diluents and fillers, diluents, including sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. The pharmaceutical compositions may be administered alone or in combination with other therapeutic agents (as indicated in the Combination Therapy section below). Such compositions are prepared in a manner well known in the pharmaceutical art (see, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa. 17th Ed. (1985); and Modern Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (G. S. Banker & C. T. Rhodes, Eds.)

The pharmaceutical compositions may be administered in either single or multiple doses by any of the accepted modes of administration of agents having similar utilities, for example as described in those patents and patent applications incorporated by reference, including rectal, buccal, intranasal and transdermal routes, by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously orally, topically, as an inhalant or via an impregnated or coated device such as a stent, for example or an artery-inserted cylindrical polymer.

One mode for administration is parenteral, particularly by injection. The forms in which the novel compositions of the present disclosure may be incorporated for administration by injection include aqueous or oil suspensions or emulsions, with sesame oil, corn oil, cottonseed oil or peanut oil, as well as elixirs, mannitol, dextrose or a sterile aqueous solution and similar pharmaceutical vehicles. Aqueous solutions in saline are also conventionally used for injection, but less preferred in the context of the present disclosure. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, and the like (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be employed. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like.

Sterile injectable solutions are prepared by incorporating a compound according to the present disclosure in the required amount in the appropriate solvent with various other ingredients as enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the general methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Oral administration is another route for administration of compounds in accordance with the disclosure. Administration may be via capsule or enteric coated tablets or the like. In making the pharmaceutical compositions that include at least one compound described herein, the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be in the form of a solid, semi-solid or liquid material (as above), which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injectable solutions and sterile packaged powders.

Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl and propylhydroxy-benzoates; sweetening agents; and flavoring agents.

The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S. Pat. Nos. 3,845,770; 4,326,525; 4,902,514; and 5,616,345. Another formulation for use in the methods of the present disclosure employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present disclosure in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile or on demand delivery of pharmaceutical agents.

In some embodiments, the compositions are formulated in a unit dosage form. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient (e.g., a tablet, capsule, ampoule). The compounds are generally administered in a pharmaceutically effective amount. In some embodiments, each dosage unit contains from 1 mg to 2 g of a compound described herein and for parenteral administration, in some embodiments, from 0.1 to 700 mg of a compound a compound described herein. It will be understood, however, that the amount of the compound actually administered usually will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight and response of the individual patient, the severity of the patient's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.

The tablets or pills of the present disclosure may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action or to protect from the acid conditions of the stomach. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents or mixtures thereof and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a facemask tent or intermittent positive pressure breathing machine. Solution, suspension or powder compositions may be administered, in some embodiments orally or nasally, from devices that deliver the formulation in an appropriate manner.

In one embodiment, this disclosure relates to a pharmaceutical composition comprising a pharmaceutically acceptable excipient or carrier and a therapeutically effective amount of the compound of Compound I as described above or a pharmaceutically acceptable salt, ester, prodrug, stereoisomer or hydrate thereof.

VI. METHODS OF USE

The solid forms of Compound I described herein can be administered to a subject suffering from a viral infection such as, but not limited to, hepatitis B virus (HBV), hepatitis C virus (HCV), and human immuno-deficiency virus (HIV) in either single or multiple doses by any of the accepted modes of administration known to those who are skilled in the art and as detailed above.

As used herein, an “agonist” is a substance that stimulates its binding partner, typically a receptor. Stimulation is defined in the context of the particular assay, or may be apparent in the literature from a discussion herein that makes a comparison to a factor or substance that is accepted as an “agonist” or an “antagonist” of the particular binding partner under substantially similar circumstances as appreciated by those of skill in the art. Stimulation may be defined with respect to an increase in a particular effect or function that is induced by interaction of the agonist or partial agonist with a binding partner and can include allosteric effects.

As used herein, an “antagonist” is a substance that inhibits its binding partner, typically a receptor. Inhibition is defined in the context of the particular assay, or may be apparent in the literature from a discussion herein that makes a comparison to a factor or substance that is accepted as an “agonist” or an “antagonist” of the particular binding partner under substantially similar circumstances as appreciated by those of skill in the art. Inhibition may be defined with respect to a decrease in a particular effect or function that is induced by interaction of the antagonist with a binding partner, and can include allosteric effects.

As used herein, a “partial agonist” or a “partial antagonist” is a substance that provides a level of stimulation or inhibition, respectively, to its binding partner that is not fully or completely agonistic or antagonistic, respectively. It will be recognized that stimulation, and hence, inhibition is defined intrinsically for any substance or category of substances to be defined as agonists, antagonists, or partial agonists.

As used herein, “intrinsic activity” or “efficacy” relates to some measure of biological effectiveness of the binding partner complex. With regard to receptor pharmacology, the context in which intrinsic activity or efficacy should be defined will depend on the context of the binding partner (e.g., receptor/ligand) complex and the consideration of an activity relevant to a particular biological outcome. For example, in some circumstances, intrinsic activity may vary depending on the particular second messenger system involved. Where such contextually specific evaluations are relevant, and how they might be relevant in the context of the present invention, will be apparent to one of ordinary skill in the art.

As used herein, modulation of a receptor includes agonism, partial agonism, antagonism, partial antagonism, or inverse agonism of a receptor.

As will be appreciated by those skilled in the art, when treating a viral infection such as HCV, HBV, or HIV, such treatment may be characterized in a variety of ways and measured by a variety of endpoints. The scope of the present invention is intended to encompass all such characterizations.

In one embodiment, the method can be used to induce an immune response against multiple epitopes of a viral infection in a human. Induction of an immune response against viral infection can be assessed using any technique that is known by those of skill in the art for determining whether an immune response has occurred. Suitable methods of detecting an immune response for the present invention include, among others, detecting a decrease in viral load or antigen in a subject's serum, detection of IFN-gamma-secreting peptide specific T cells, and detection of elevated levels of one or more liver enzymes, such as alanine transferase (ALT) and aspartate transferase (AST). In one embodiment, the detection of IFN-gamma-secreting peptide specific T cells is accomplished using an ELISPOT assay. Another embodiment includes reducing the viral load associated with HBV infection, including a reduction as measured by PCR testing.

In some embodiments, the present invention provides a method of treating a viral infection, comprising administering to a human in need thereof, a therapeutically effective amount of a crystalline form of Compound I or pharmaceutical composition of the present invention. In some embodiments, the present invention provides a crystalline form of Compound I for use in the treatment of a viral infection, comprising administering a therapeutically effective amount of a crystalline form of Compound I or a pharmaceutical composition of the present invention. In some embodiments, the present invention provides use of a crystalline form of Compound I for the treatment of a viral infection. In some embodiments, the present invention provides use of a crystalline form of Compound I for the manufacture of a medicament for the treatment of a viral infection.

In another aspect, the present invention provides methods for treating a hepatitis B viral infection or a hepatitis C viral infection, wherein each of the methods includes the step of administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of a crystalline form of Compound I. Typically, the human subject is suffering from a chronic hepatitis B infection or a chronic hepatitis C infection, although it is within the scope of the present invention to treat people who are acutely infected with HBV or HCV.

In some embodiments, the present invention provides a crystalline form of Compound I for use in the treatment of a hepatitis B viral infection or a hepatitis C viral infection. In some embodiments, the present invention provides use of a crystalline form of Compound I for the manufacture of a medicament for the treatment of a hepatitis B viral infection or a hepatitis C viral infection.

In some embodiments, the present invention provides a crystalline form of Compound I for use in the treatment of a hepatitis B viral infection. In some embodiments, the present invention provides use of a crystalline form of Compound I for the manufacture of a medicament for the treatment of a hepatitis B viral infection.

Treatment in accordance with the present invention typically results in the stimulation of an immune response against HBV or HCV in a human being infected with HBV or HCV, respectively, and a consequent reduction in the viral load of HBV or HCV in the infected person. Examples of immune responses include production of antibodies (e.g., IgG antibodies) and/or production of cytokines, such as interferons, that modulate the activity of the immune system. The immune system response can be a newly induced response, or can be boosting of an existing immune response. In particular, the immune system response can be seroconversion against one or more HBV or HCV antigens.

The viral load can be determined by measuring the amount of HBV DNA or HCV DNA present in the blood. For example, blood serum HBV DNA can be quantified using the Roche COBAS Amplicor Monitor PCR assay (version 2.0; lower limit of quantification, 300 copies/mL [57 IU/mL]) and the Quantiplex bDNA assay (lower limit of quantification, 0.7 MEq/mL; Bayer Diagnostics, formerly Chiron Diagnostics, Emeryville, Calif.). The amount of antibodies against specific HBV or HCV antigens (e.g., hepatitis B surface antigen (HBsAG)) can be measured using such art-recognized techniques as enzyme-linked immunoassays and enzyme-linked immunoabsorbent assays. For example, the amount of antibodies against specific HBV or HCV antigens can be measured using the Abbott AxSYM microparticle enzyme immunoassay system (Abbott Laboratories, North Chicago, Ill.).

Compound I can be administered by any useful route and means, such as by oral or parenteral (e.g., intravenous) administration. Therapeutically effective amounts of Compound I are from about 0.00001 mg/kg body weight per day to about 10 mg/kg body weight per day, such as from about 0.0001 mg/kg body weight per day to about 10 mg/kg body weight per day, or such as from about 0.001 mg/kg body weight per day to about 1 mg/kg body weight per day, or such as from about 0.01 mg/kg body weight per day to about 1 mg/kg body weight per day, or such as from about 0.05 mg/kg body weight per day to about 0.5 mg/kg body weight per day, or such as from about 0.3 μg to about 30 mg per day, or such as from about 30 μg to about 300 μg per day.

Therapeutically effective amounts of Compound I are also from about 0.01 mg per dose to about 1000 mg per dose, such as from about 0.01 mg per dose to about 100 mg per dose, or such as from about 0.1 mg per dose to about 100 mg per dose, or such as from about 1 mg per dose to about 100 mg per dose, or such as from about 1 mg per dose to about 10 mg per dose. Other therapeutically effective amounts of Compound I are about 1 mg per dose, or about 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or about 100 mg per dose. Other therapeutically effective amounts of Compound I are about 100 mg per dose, or about 125, 150, 175, 200, 225, 250, 275, 300, 350, 400, 450, or about 500 mg per dose. A single dose can be administered hourly, daily, or weekly. For example, a single dose can be administered once every 1 hour, 2, 3, 4, 6, 8, 12, 16 or once every 24 hours. A single dose can also be administered once every 1 day, 2, 3, 4, 5, 6, or once every 7 days. A single dose can also be administered once every 1 week, 2, 3, or once every 4 weeks. A single dose can also be administered once every month.

The frequency of dosage of Compound I will be determined by the needs of the individual patient and can be, for example, once per day or twice, or more times, per day. Administration of Compound I continues for as long as necessary to treat the HBV or HCV infection. For example, Compound I can be administered to a human being infected with HBV or HCV for a period of from 20 days to 180 days or, for example, for a period of from 20 days to 90 days or, for example, for a period of from 30 days to 60 days.

Administration can be intermittent, with a period of several or more days during which a patient receives a daily dose of Compound I, followed by a period of several or more days during which a patient does not receive a daily dose of Compound I. For example, a patient can receive a dose of Compound I every other day, or three times per week. Again by way of example, a patient can receive a dose of Compound I each day for a period of from 1 to 14 days, followed by a period of 7 to 21 days during which the patient does not receive a dose of Compound I, followed by a subsequent period (e.g., from 1 to 14 days) during which the patient again receives a daily dose of Compound I. Alternating periods of administration of Compound I, followed by non-administration of Compound I, can be repeated as clinically required to treat the patient.

As described more fully herein, crystalline forms of Compound I can be administered with one or more additional therapeutic agent(s) to a human being infected with hepatitis B virus or hepatitis C virus. The additional therapeutic agent(s) can be administered to the infected human being at the same time as the crystalline form of Compound I, or before or after administration of the crystalline form of Compound I. In some embodiments, the present invention provides a crystalline form of Compound I, for use in a method of treating or preventing a hepatitis B viral infection, wherein the crystalline form of Compound I is administered simultaneously, separately or sequentially with one or more additional therapeutic agents for treating a hepatitis B viral infection. In some embodiments, the present invention provides use of a crystalline form of Compound I for the manufacture of a medicament for the treatment of a hepatitis B viral infection, wherein the crystalline form of Compound I is administered simultaneously, separately or sequentially with one or more additional therapeutic agents for treating a hepatitis B viral infection.

In another aspect, the present invention provides a method for ameliorating a symptom associated with an HBV infection or HCV infection, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of the crystalline form of Compound I, wherein the therapeutically effective amount is sufficient to ameliorate a symptom associated with the HBV infection or HCV infection. Such symptoms include the presence of HBV virus particles (or HCV virus particles) in the blood, liver inflammation, jaundice, muscle aches, weakness and tiredness.

In some embodiments, the present invention provides a crystalline form of Compound I for use in ameliorating a symptom associated with an HBV infection or HCV infection, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of the crystalline form of Compound I, wherein the therapeutically effective amount is sufficient to ameliorate a symptom associated with the HBV infection or HCV infection. In some embodiments, the present invention provides use of a crystalline form of Compound I for the manufacture of a medicament for the ameliorating a symptom associated with an HBV infection or HCV infection, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of the crystalline form of Compound I, wherein the therapeutically effective amount is sufficient to ameliorate a symptom associated with the HBV infection or HCV infection

In a further aspect, the present invention provides a method for reducing the rate of progression of a hepatitis B viral infection, or a hepatitis C virus infection, in a human being, wherein the method comprises administering to a human subject infected with hepatitis B virus or hepatitis C virus a therapeutically effective amount of Compound I, or a pharmaceutically acceptable salt thereof, wherein the therapeutically effective amount is sufficient to reduce the rate of progression of the hepatitis B viral infection or hepatitis C viral infection. The rate of progression of the infection can be followed by measuring the amount of HBV virus particles or HCV virus particles in the blood.

In another aspect, the present invention provides a method for reducing the viral load associated with HBV infection or HCV infection, wherein the method comprises administering to a human being infected with HBV or HCV a therapeutically effective amount of Compound I, or a pharmaceutically acceptable salt thereof, wherein the therapeutically effective amount is sufficient to reduce the HBV viral load or the HCV viral load in the human being.

In a further aspect, the present invention provides a method of inducing or boosting an immune response against Hepatitis B virus or Hepatitis C virus in a human being, wherein the method comprises administering a therapeutically effective amount of Compound I, or a pharmaceutically acceptable salt thereof, to the human being, wherein a new immune response against Hepatitis B virus or Hepatitis C virus is induced in the human being, or a preexisting immune response against Hepatitis B virus or Hepatitis C virus is boosted in the human being. Seroconversion with respect to HBV or HCV can be induced in the human being. Examples of immune responses include production of antibodies, such as IgG antibody molecules, and/or production of cytokine molecules that modulate the activity of one or more components of the human immune system.

Induction of seroconversion against HCV or HBV in patients chronically infected with either of these viruses is an unexpected property of Compound I. In clinical practice, an HBV patient, or HCV patient, is treated with Compound I, alone or in combination with one or more other therapeutic agents, until an immune response against HBV or HCV is induced or enhanced and the viral load of HBV or HCV is reduced. Thereafter, although the HBV or HCV virus may persist in a latent form in the patient's body, treatment with Compound I can be stopped, and the patient's own immune system is capable of suppressing further viral replication. In patients treated in accordance with the present invention and who are already receiving treatment with an antiviral agent that suppresses replication of the HBV virus or HCV virus, there may be little or no detectable viral particles in the body of the patient during treatment with the antiviral agent(s). In these patients, seroconversion will be evident when the antiviral agent(s) is no longer administered to the patient and there is no increase in the viral load of HBV or HCV.

In the practice of the present invention, an immune response is induced against one or more antigens of HBV or HCV. For example, an immune response can be induced against the HBV surface antigen (HBsAg), or against the small form of the HBV surface antigen (small S antigen), or against the medium form of the HBV surface antigen (medium S antigen), or against a combination thereof. Again by way of example, an immune response can be induced against the HBV surface antigen (HBsAg) and also against other HBV-derived antigens, such as the core polymerase or x-protein.

Induction of an immune response against HCV or HBV can be assessed using any technique that is known by those of skill in the art for determining whether an immune response has occurred. Suitable methods of detecting an immune response for the present invention include, among others, detecting a decrease in viral load in a subject's serum, such as by measuring the amount of HBV DNA or HCV DNA in a subject's blood using a PCR assay, and/or by measuring the amount of anti-HBV antibodies, or anti-HCV antibodies, in the subject's blood using a method such as an ELISA.

Additionally, the compounds of this invention may be useful in the treatment of cancer or tumors (including dysplasias, such as uterine dysplasia). These includes hematological malignancies, oral carcinomas (for example of the lip, tongue or pharynx), digestive organs (for example esophagus, stomach, small intestine, colon, large intestine, or rectum), liver and biliary passages, pancreas, respiratory system such as larynx or lung (small cell and non-small cell), bone, connective tissue, skin (e.g., melanoma), breast, reproductive organs (uterus, cervix, testicles, ovary, or prostate), urinary tract (e.g., bladder or kidney), brain and endocrine glands such as the thyroid. In summary, the compounds of this invention are employed to treat any neoplasm, including not only hematologic malignancies but also solid tumors of all kinds.

Hematological malignancies are broadly defined as proliferative disorders of blood cells and/or their progenitors, in which these cells proliferate in an uncontrolled manner. Anatomically, the hematologic malignancies are divided into two primary groups: lymphomas—malignant masses of lymphoid cells, primarily but not exclusively in lymph nodes, and leukemias—neoplasm derived typically from lymphoid or myeloid cells and primarily affecting the bone marrow and peripheral blood. The lymphomas can be sub-divided into Hodgkin's Disease and Non-Hodgkin's lymphoma (NHL). The latter group comprises several distinct entities, which can be distinguished clinically (e.g. aggressive lymphoma, indolent lymphoma), histologically (e.g. follicular lymphoma, mantle cell lymphoma) or based on the origin of the malignant cell (e.g. B lymphocyte, T lymphocyte). Leukemias and related malignancies include acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL). Other hematological malignancies include the plasma cell dyscrasias including multiple myeloma, and the myelodysplastic syndromes.

VII. Combination Therapy

Subjects being treated by administration of the solid forms of Compound I described herein can benefit from treatment with additional therapeutic agents that are effective in treating HCV, or enhance the anti-HCV therapeutic effect of Compound I forms, in accordance with some embodiments.

The solid forms (polymorphs, solvates and hydrates) of Compound I were characterized by a variety of the following methods.

X-ray Powder Diffraction (XRPD). The Rigaku Smart-Lab® X-ray diffraction system was configured for reflection BraggBrentano geometry using a line source X-ray beam. The x-ray source is a Cu Long Fine Focus tube that was operated at 40 kV and 44 mA. That source provides an incident beam profile at the sample that changes from a narrow line at high angles to a broad rectangle at low angles. Beam conditioning slits were used on the line X-ray source to ensure that the maximum beam size is less than 10 mm both along the line and normal to the line. The Bragg-Brentano geometry is a para-focusing geometry controlled by passive divergence and receiving slits with the sample itself acting as the focusing component for the optics. The inherent resolution of Bragg-Brentano geometry is governed in part by the diffractometer radius and the width of the receiving slit used. Typically, the Rigaku Smart-Lab is operated to give peak widths of 0.1°2θ or less. The axial divergence of the X-ray beam is controlled by 5.0-degree Soller slits in both the incident and diffracted beam paths.

Powder samples were prepared in a low background Si holder using light manual pressure to keep the sample surfaces flat and level with the reference surface of the sample holder. The single-crystal, Si, low-background holder has a small circular recess (7 mm diameter and about 1 mm depth) that holds between 5 and 10 mg of powdered material. Each sample was analyzed from 2 to 40°2θ using a continuous scan of 3°2θ per minute with an effective step size of 0.02°2θ.

Solubility Estimations. Solubilities were estimated by treating a weighed sample of Compound I with measured aliquots of the test solvent at ambient temperature, with shaking and/or sonication between aliquots. Dissolution was determined by visual inspection. Solubility numbers were calculated by dividing the total amount of solvent used to dissolve the sample by the weight of the sample. The actual solubilities may be greater than the numbers calculated because of the use of solvent aliquots that were too large or because of slow dissolution rates. The solubility number is expressed as “less than” if dissolution did not occur during the experiment. The solubility number is expressed as “greater than” if dissolution occurred on addition of the first solvent aliquot.

Differential Scanning calorimetry (DSC). DSC analyses were carried out using a TA Instruments Q2000 instrument. The instrument temperature calibration was performed using indium. The DSC cell was kept under a nitrogen purge of ˜50 mL per minute during each analysis. The sample was placed in a standard, crimped, aluminum pan and was heated from 20° C. to 350° C. at a rate of 10° C. per minute.

Thermogravimetric (TGA) Analysis. The TGA analysis was carried out using a TA Instruments Q50 instrument. The instrument balance was calibrated using class M weights and the temperature calibration was performed using alumel. The nitrogen purge was ˜40 ml per minute at the balance and ˜60 ml per minute at the furnace. Each sample was placed into a pretared platinum pan and heated from 20° C. to 350° C. at a rate of 10° C. per minute.

Karl Fischer (KF) Analyses. Karl Fischer analyses were carried out using a Mettler-Toledo C20 Coulometric KF titrator. The instrument was calibrated with a standard of known water concentration.

Dynamic Vapor Sorption (DVS). DVS analyses were carried out in a TA Instruments 05000 Dynamic Vapor Sorption analyzer. The instrument was calibrated with standard weights and a sodium bromide standard for humidity. Samples were analyzed at 25° C. with a maximum equilibration time of 60 minutes in 10% relative humidity (RH) steps from 5 to 95% RH (adsorption cycle) and from 95 to 5% RH (desorption cycle).
